Description

Die Erfindung betrifft ein Steckergehäuse für ein optisches Steckerpaar gemäss dem Oberbegriff von Anspruch 1. Bei diesen sogenannten Duplex-Steckern ist es für die Herstellung einer möglichst dämpfungsarmen Lichtübertragung an der Steckverbindung von grosser Bedeutung, dass die beiden Steckerteile nicht starr parallel nebeneinander gehalten werden, sondern dass jedes Steckerteil in einem begrenzten Mass eine Relativbewegung ausführen kann. Dies gilt insbesondere auch für Steckverbindungen des Push-Pull-Typs, der international unter der Typenbezeichnung SC genormt ist.The invention relates to a connector housing for an optical Plug pair according to the preamble of claim 1. In these so-called duplex plugs, it is for the manufacture of a low-loss light transmission at the connector of great importance that the two connector parts not rigidly held parallel next to each other, but that each connector part has a relative movement to a limited extent can perform. This applies in particular to Push-pull type connectors, which are used internationally the type designation SC is standardized.

Es ist bereits bekannt, die Gehäuseteile so auszubilden, dass je zwei Gehäuseteile mit Hilfe einer Verbindungsklammer zusammengehalten werden können. Durch die WO 94/24592 ist beispielsweise eine Verbindungsanordnung bekannt geworden, bei welcher eine zweiteilige Verbindungsklammer auf die Gehäuseteile aufgeschnappt werden kann. Die Verbindung erfolgt über eine bogenartige Materialbrücke an jeder Klammerhälfte. Ein anderes Verbindungsprinzip ist in der US-A 5,123,071 beschrieben. Dort werden die Gehäuseteile mittels E-förmiger Klammern zusammengehalten, wobei zwei Klammern ineinander einrastbar sind, die Gehäuseteile jedoch spezielle Führungsflächen aufweisen müssen.It is already known to design the housing parts so that two housing parts each with the help of a connecting clip can be held together. Through WO 94/24592 for example a connection arrangement has become known, in which a two-part connecting bracket on the Housing parts can be snapped on. The connection is made over an arched material bridge on each bracket half. Another connection principle is in US-A 5,123,071. There the housing parts are by means of E-shaped brackets held together, with two brackets can be snapped into each other, but the housing parts are special Must have guide surfaces.

Aus der EP-A 597 501 ist es aber auch bereits bekannt, zwei Gehäuseteile ohne zusätzliche Hilfsmittel direkt über einen flexiblen Materialsteg einstückig miteinander zu verbinden. Die Verbindung besteht dabei aus einem etwa Z-förmigen Materialsteg.However, two are already known from EP-A 597 501 Housing parts directly without additional aids to connect the flexible material web in one piece. The connection consists of an approximately Z-shaped material web.

DE-C1-43 02 826 offenbart eine H-förmige Halteklammer, in die die einzelnen optischen Steckverbinder-Gehäuse mittels einer Einrastbewegung auf einer durch die beiden Steckverbinder-Gehäuse verlaufenden Ebene und quer zur Längsrichtung der Gehäuse einrastbar sind.DE-C1-43 02 826 discloses an H-shaped retaining clip into which the individual optical connector housing by means of a snap-in movement on a level running through the two connector housings and are latched transversely to the longitudinal direction of the housing.

Separate Verbindungsklammern haben den Nachteil, dass nicht nur die Gehäuseteile speziell angepasst werden müssen, sondern dass auch noch zusätzliche Bauteile erforderlich sind, die leicht verloren gehen können. Je nach Ausbildung der Klammern ist die Verbindungsstabilität zudem nicht befriedigend. Aber auch die einstückige Ausbildung der beiden Gehäuseteile ist mit erheblichen Nachteilen verbunden, da relativ aufwenige Werkzeuge für die Herstellung erforderlich sind.Separate connecting brackets have the disadvantage that not only do the housing parts have to be specially adapted, but that additional components are also required are that can easily get lost. Depending on the training of the brackets, the connection stability is also unsatisfactory. But also the one-piece training of the two Housing parts is associated with considerable disadvantages because relatively expensive tools required for production are.

Es ist daher eine Aufgabe der Erfindung, ein Steckergehäuse der eingangs genannten Art zu schaffen, das die Vorteile separater Gehäuseteile aufweist, ohne dass für die Verbindung zusätzliche Klammern erforderlich sind. Das Verbindungsmittel soll ausserdem eine sichere Verbindung gewährleisten, wobei jedoch ein genügender Bewegungsspielraum verbleibt. Die beim Einstecken und Ausstecken auftretenden Druck- und Zugbelastungen sollen sich zudem nicht negativ auf die Stabilität des Verbindungsmittels auswirken. Diese Aufgabe wird erfindungsgemäss mit einem Steckergehäuse gelöst, das die Merkmale im Anspruch 1 aufweist.It is therefore an object of the invention to provide a connector housing of the kind mentioned at the beginning to create the advantages has separate housing parts without the connection additional brackets are required. The lanyard should also ensure a secure connection, whereby however, there is sufficient room for maneuver. The at Pushing and unplugging pressure and tensile loads should also not negatively affect stability of the lanyard. This object is achieved according to the invention solved with a connector housing that features in claim 1.

Der Schnappverschluss löst das Problem der Verbindung ohne zusätzliche Bauteile. Die Einrastung auf einer durch die beiden Gehäuseteile verlaufenden Ebene und quer zur Längsrichtung der Gehäuseteile ermöglicht die Schaffung günstiger Voraussetzungen für die Bewegungsmöglichkeit und die mechanische Belastung der beiden Gehäuseteile.The snap lock solves the connection problem without additional components. The snap on one by the two housing parts running level and transverse to the longitudinal direction of the housing parts enables the creation of cheaper Requirements for the possibility of movement and the mechanical Loading of the two housing parts.

Besonders vorteilhaft weist der Schnappverschluss am ersten Gehäuseteil ein Sperrklinkenpaar und am zweiten Gehäuseteil ein Sperrleistenpaar auf. Die Klinken und Leisten erstrecken sich über eine bestimmte Länge und ergeben so eine stabile Verbindung. Alternativ wären aber auch andere Schnappverschlüsse denkbar wie z.B. Schnappwulste oder Schnappnocken.The snap closure on the first one is particularly advantageous Housing part a pair of pawls and on the second housing part a pair of locking bars. The pawls and ledges extend over a certain length and thus result in a stable Connection. Alternatively, other snap locks would also be conceivable such as Snap beads or snap cams.

Die Gehäuseteile können etwa quaderförmig ausgebildet sein und das Steckergehäuse erscheint insgesamt als homogene Einheit, wenn das Sperrklinkenpaar und das Sperrleistenpaar an einander zugewandten Längsseiten der Gehäuseteile angeordnet sind, wobei das aussenliegende Sperrklinkenpaar im eingerasteten Zustand das innenliegende Sperrleistenpaar überlappt. Dabei sind die Sperrklinken des Sperrklinkenpaars vorzugsweise an federnden Zungen angeordnet, welche in der Ebene paralleler Seitenwände am ersten Gehäuseteil verlaufen. Die Sprerrklinken und Zungen überdecken auf diese Weise die eigentliche Schnappverbindung, so dass Sie von aussen nicht ohne weiteres zugänglich ist. Beim Anfassen des Steckergehäuses an den parallelen Seitenwänden werden die Sperrklinken gegen die Sperrleisten gepresst, was die Verbindung noch verstärkt.The housing parts can be approximately cuboid and the connector housing appears overall as homogeneous Unit when the pair of pawls and the pair of locking bars arranged on mutually facing longitudinal sides of the housing parts are, the outer pair of pawls in the engaged Condition the pair of internal locking strips overlaps. The pawls of the pair of pawls are preferably arranged on resilient tongues, which in the Level parallel side walls on the first housing part. The locking pawls and tongues thus cover the actual snap connection, so you don't from the outside is easily accessible. When touching the connector housing on the parallel side walls are the pawls pressed against the locking bars, what the connection still reinforced.

Eine besonders hohe Stabilität der Schnappverbindung in Axialrichtung der Steckerteile ergibt sich, wenn auf beiden Seiten der Zungen und im Abstand zu diesen Stützelemente an der Längsseite des ersten Gehäuseteils angeordnet sind, wobei zwischen den Stützelementen und den Zungen Ausnehmungen gebildet werden, und wenn auf beiden Seiten der Sperrleisten und anschliessend an diese Führungselemente an der Längsseite des zweiten Gehäuseteils angeordnet sind, welche in die Ausnehmungen des ersten Gehäuseteils eingreifen. Auf diese Weise ergibt sich eine Art Verschachtelung der beiden Gehäuseteile, wobei je nach Dimensionierung der Ausnehmungen bzw. der Führungselemente ein maximales Spiel in Längsrichtung zwischen den beiden Gehäuseteilen zugelassen werden kann. Nach Ueberwindung dieses Spiels werden Kräfte in Längsrichtung, die am einen Gehäuseteil angreifen unmittelbar auf das andere Gehäuseteil übertragen.A particularly high stability of the snap connection in Axial direction of the connector parts results when on both Sides of the tongues and at a distance from these support elements the long side of the first housing part are arranged, wherein recesses between the support elements and the tongues are formed, and if on both sides of the locking bars and then these guide elements on the long side of the second housing part are arranged, which in the Engage recesses in the first housing part. To this This results in a kind of nesting of the two housing parts, depending on the dimensioning of the recesses or the guide elements a maximum play in the longitudinal direction can be allowed between the two housing parts. After overcoming this game, forces in the longitudinal direction, that attack on a housing part directly on the transfer other housing part.

Gegen Verdrehung können die beiden Gehäuseteile gesichert werden, wenn in den Stützelementen in der Einrastebene verlaufende Schlitze angeordnet sind und wenn die Führungselemente Seitenlappen aufweisen, welche in die Schlitze eingreifen. Dabei kann aber trotzdem eine bestimmte Elastizität erhalten bleiben, wenn die Führungselemente und die Seitenlappen in der Einrastebene geteilt ausgebildet sind.The two housing parts can be secured against rotation become, if extending in the support elements in the locking plane Slots are arranged and when the guide elements Have side tabs which engage in the slots. However, it can still have a certain elasticity are retained if the guide elements and the side tabs are divided in the snap-in plane.

Aus den Figuren 1 und 2 ist der grundsätzliche Aufbau eines erfindungsgemässen Steckergehäuses ersichtlich, während weitere Einzelheiten aus den nachfolgenden Schnittdarstellungen ersichtlich sind. Das Steckergehäuse 1 besteht im wesentlichen aus einem ersten Gehäuseteil 2 und aus einem zweiten Gehäuseteil 3, vorzugsweise aus einem Kunststoffmaterial. Die beiden Gehäuseteile sind auch so ausgebildet, dass sie ohne zusätzliche Schieber in einem möglichst einfachen Spritzgusswerkzeug hergestellt werden können.FIGS. 1 and 2 show the basic structure of a plug housing according to the invention can be seen while further details from the sectional views below are evident. The connector housing 1 consists essentially from a first housing part 2 and from a second Housing part 3, preferably made of a plastic material. The two housing parts are also designed so that they without Additional slides in the simplest possible injection molding tool can be produced.

Die beiden etwa quaderförmigen Gehäuseteile sind dazu bestimmt ein erstes Steckerteil 4 und ein zweites Steckerteil 5 aufzunehmen. Dabei handelt es sich um Steckerteile an sich bekannter Bauart, welche derart in die beiden Gehäuseteile 2 und 3 eingeprellt werden können, dass sie mit axialem Spiel darin festgehalten werden. Gehäuseteile und Steckerteile bilden insgesamt eine optische Steckereinheit, welche nach dem Push-Pull-Prinzip gesteckt werden kann. Dazu sind an den Gehäuseteilen Oeffnungen 20 und Entriegelungsrampen 21 vorgesehen, welche mit parallelen Halteklauen an einem hier nicht dargestellten Buchsenteil zusammenwirken. Bei einem Zug am Lichtwellenleiterkabel kann die Steckverbindung nicht gelöst werden. Ein Zug am Steckergehäuse bewirkt jedoch eine Relativverschiebung zwischen dem Steckergehäuse und den Steckerteilen, wobei die Entriegelungsrampen 21 in Aktion treten und die Verriegelung lösen. Das Push-Pull-Steckprinzip ist dem Fachmann jedoch längst bekannt.The two roughly cuboid housing parts are intended for this purpose a first plug part 4 and a second plug part 5 to record. These are plug parts per se known type, which in this way in the two housing parts 2nd and 3 can be injected with axial play be held in it. Housing parts and plug parts form an optical connector unit, which according to the push-pull principle can be inserted. For this purpose, the Housing parts openings 20 and unlocking ramps 21 are provided, which with parallel claws on one here Interact not shown socket part. On a train the connector on the fiber optic cable cannot be solved. A pull on the connector housing causes one Relative displacement between the connector housing and the Plug parts, the unlocking ramps 21 in action kick and release the lock. The push-pull plug-in principle has long been known to the person skilled in the art.

Auf den Gehäuseteilen 2 und 3 sind Positioniernasen 22 angeordnet, welche ein lagerichtiges Einstecken des Duplexsteckers in die Buchse gewährleisten. Wie insbesondere aus Figur 4 ersichtlich ist, weist das erste Gehäuseteil 2 ein Sperrklinkenpaar 6 auf, wobei die einzelnen Sperrklinken an federnden Zungen 10 befestigt sind. Diese Zungen verlaufen in der Ebene der parallelen Seitenwände 11, 11'. Im Abstand zu den Zungen 10 sind an der Längsseitenwand 8 Stützelemente 13 angeordnet, deren Tiefe der Tiefe der Zungen entspricht. Zwischen den Zungen und den Stützelementen werden dadurch Ausnehmungen 14 gebildet. In den Stützelementen sind ausserdem Schlitze 16 angeordnet, welche parallel zu den Seitenwänden 11 bzw. 11' verlaufen. Diese Schlitze sind nicht durchgehend, sondern öffnen sich nur gegen die Zungen 10.Positioning lugs 22 are arranged on the housing parts 2 and 3, which is a correct insertion of the duplex connector ensure in the socket. How especially out FIG. 4 shows the first housing part 2 Pawl pair 6 on, with the individual pawls on resilient tongues 10 are attached. These tongues run in the plane of the parallel side walls 11, 11 '. At a distance from the tongues 10 are 8 support elements 13 on the longitudinal side wall arranged, the depth of which corresponds to the depth of the tongues. As a result, between the tongues and the support elements Recesses 14 formed. In the support elements are also Slits 16 arranged which are parallel to the side walls 11 and 11 'run. These slots are not continuously, but only open against the tongues 10.

Die Stützelemente auf beiden Seiten der Zungen sind mittels einer Anschlagleiste 18 miteinander verbunden. Wie insbesondere aus Figur 3 hervorgeht, verläuft diese Anschlagleiste etwa in der Ebene der Längsseitenwand 8.The support elements on both sides of the tongues are by means of a stop bar 18 connected to each other. How in particular emerges from Figure 3, this stop bar runs approximately in the plane of the longitudinal side wall 8.

Die Konfiguration des zweiten Gehäuseteils 3 ergibt sich im Detail aus den Figuren 7 bis 10. An der Längsseitenwand 9 sind Führungselemente 15 angeordnet, welche in die Ausnehmung 14 am ersten Gehäuseteil mit Spiel passen. Diese Führungselemente schliessen sich unmittelbar an das Sperrleistenpaar 7 an, wobei die einzelnen Sperrleisten auch noch über einen U-förmigen Verbindungssteg 19 miteinander verbunden sind. Dadurch ergibt sich eine relativ starre Ausbildung des Sperrleistenpaars. Seitlich an die Führungselemente 15 schliessen sich Seitenlappen 17 an, welche in die Schlitze 16 des ersten Gehäuseteils mit Spiel passen. In der Ebene der Seitenwände 12 bzw. 12' sind jedoch die Führungselemente 15 und die Seitenlappen 17 geteilt ausgebildet. Dies ergibt sich besonders deutlich aus Figur 7. Dadurch bleibt eine gewisse Elastizität erhalten, wenn die beiden Gehäuseteile zusammengerastet sind.The configuration of the second housing part 3 results in Detail from FIGS. 7 to 10. On the long side wall 9 guide elements 15 are arranged, which in the recess 14 fit on the first housing part with play. These leadership elements immediately connect to the pair of locking bars 7, the individual locking bars also via a U-shaped connecting web 19 are interconnected. This results in a relatively rigid design of the locking bar pair. Close on the side of the guide elements 15 side tabs 17, which in the slots 16 of the first Fit part of the housing with play. In the level of the side walls 12 and 12 ', however, are the guide elements 15 and Side tabs 17 formed divided. This is particularly the case clear from Figure 7. This leaves a certain elasticity received when the two housing parts snapped together are.

Das Ineinandergreifen der einzelnen Bauteile im zusammengerasteten Zustand ergibt sich aus den Figuren 11 bis 13. Insbesondere die Figur 12 zeigt dabei, wie das Sperrklinkenpaar 6 hinter dem Sperrleistenpaar 7 einrastet. Die Flanken der Sperrklinken und der Sperrleisten sind angeschrägt, um ein Zusammenrasten ohne übermässigen Kraftaufwand zu ermöglichen. Die Sperrleisten liegen stirnseitig an der Anschlagleiste 18 an, wodurch eine gute Seitenstabilität erreicht wird. Die Seitenlappen 17 greifen fast passgenau in die Schlitze 16, wobei aber trotzdem eine geringe Kippbewegung zwischen den beiden Gehäuseteilen möglich bleibt.The interlocking of the individual components in the locked State results from FIGS. 11 to 13. In particular, FIG. 12 shows how the pair of pawls 6 engages behind the pair of locking bars 7. The flanks the pawls and locking bars are chamfered to to allow a snap together without excessive effort. The locking bars are located on the end face of the stop bar 18 on, which provides good lateral stability becomes. The side tabs 17 engage almost exactly in the Slits 16, but still a slight tilting movement remains possible between the two housing parts.

In der Z-Achse (Figur 2) ist nur ein relativ geringes Spiel vorhanden, während in der X-Achse die beiden Gehäuseteile federnd zusammengehalten werden. In der Y-Achse sind geringe Kippbewegungen möglich.There is only relatively little play in the Z axis (FIG. 2) present, while in the X-axis the two housing parts be held together resiliently. In the Y axis there are few Tilting movements possible.
